Tocllwhomit mayconcem:

Be it known that I, PERRY S. BAUER, a citizen of" the United States, residing. at Chicago, in the county of; Cook and State of Illinois, have invented certain new and useful Improvements in Bandage-Clips, of which thefollowingis a specification.

This invention` is especially designed for surgicalbandage rolls to preventthe materialfrompunwinding in greater amount than required. for immediate use and thereby assist in preserving its antiseptic condition.

Surgicall bandages are customarily pro videdin roll form from which dressings are ordinarily applied by disposing, thefree end of the bandage forming-` the roll over the wound and wrapping the bandage about the wounded part before the portion of the bandage thusbeing used. is cut from the roll.

a number of times, each time being passed from one hand to the other of the person performing the dressing. Moreover, during this operation the roll must be unrolled by the person dressing the wound as it is wound about the said part. In thus unwinding the roll and in passing it from hand to hand the roll frequently slips from the hand of the operator to the floor, where it rolls about and unwinds. Such an accident in addition to the inconvenience caused in again obtaining the roll exposes the patient to possible infection of the wound from germs collected by the bandage while 1n contact with the floor.

One of the principal objects of my invention is to provide a clip for a bandage roll which will readily allow the material to be unwound therefrom in a proper manner but which will prevent unwinding of any appreciable length of material should the roll slip or be dropped as hereinbefore described.

A further object of the invent-ion is to provide a clip for a bandage roll which may be positioned thereon after the material has been wound to form the roll and which may be used as a guide to permit accurate rewinding of the roll should any unrequired portion be unwound therefrom.

An additional object of the invention is to provide a clip for a bandage roll which will remove from the ends of the roll any loose threads that may be pulled from the fabric.

Such an operation necessitates, that` the roll be passed around the wounded,partA A still,Y further object of the invention is to provide aclip` ofthe character described which willbe simple in construction, cheap tomanufacture, and which will efficiently perform its.l functions regardless of the amount of bandage remainingin the roll.

Additional objects and advantages ofthe invention will be apparent.` as it is better understood from the follow-ing description in connection with the accompanying drawing` disclosing one preferred embodiment thereof.

On the drawing: Figure l is a perspective view of alclip made in pursuance of my invention positioned upon arOlledbandage; Fig. 2 isa perspective view ofthe clip shown inFig. 1,.and Fig. dma-transverse central sectional view of the same.

Referring. tothedrawing, aclip lis posi- ',tioned upon a bandage roll 5, the bandage Vbeing, shown as rolled upon itself without a central core or spool, although it will be apparent that such a core or spool may be provided if desired. In the present embodiment of the invention the clip is composed of a singleA piece of wire having each of its ends bent as at 6 through an angle greater than 901o to provide a pair of arms 7, disposed in substantially the same plane and inclined with respect to the main or top portion 8 and to each other. The ends of these arms are bent inwardly at right angles to the arms to provide fingers 9 which are adapted to be pivotally engaged within the center of the bandage roll 5. The length of the top portion 8 should be substantially equal to the width of the bandage. When the clip is positioned on the roll the inclined arms T will press tightly against the ends of the roll, producing a strong frictional engagement therebetween. As the bandage is unwound by a person dressing` a wound, the clip must be moved about its pivotal axis at the center of the roll against the frictional resistance provided by the engagement of the arms with the ends of the roll. It will be apparent, therefore, that when the arms are bent as hereinbefore described prior to the positioning of the clips upon the roll this frictional resistance will be sufficient to prevent appreciable unwinding of the roll should it slip from the hand of the user while still permitting the user to easily unwind the bandage against the said resistance.

The adjacent faces of the arms may be roughened or lrnurled, as shown at lO in Fig. 3, in order that the arms when moved around the bandage in unwinding the same will scrape any loose threads from the ends of the roll. The roughened faces l0 serve also to increase the frictional engagement between the arms and the ends of the roll, and in this way aid in preventing the inadvertent or excessive unwinding of the bandage.

It will be manifest that the clip will efficiently perform its functions regardless of the amount of material removed from the roll, as the frictional engagement between the arms and the ends of the roll extends to the center of the roll2 and is produced by the resiliency of the arms which is a constant force, the removal of the outermost layers serving only to increase the frictional engagement between the reduced ends of the roll and the portions 'of the arms engaging them. It will be apparent also that a clip made in pursuance of my invention may be cheaply vmade and positioned upon rolls after they are formed7 and that should the nserof the bandage unwind more than is desirable the undesired portion may be ac l curately rewound upon the roll by turning the clip about the roll as the bandage is wound, whereby the arms will compel the edges of the bandage to aline with the ends of the roll.

I claim A clip for a bandage roll comprising a top portion7 and a flexible arm at each end of the said portion, each of said arms being disposed at an acute angle with respect to the top portion and having its inner face roughened, the free ends of the said arms being formed to be inserted within the ends of a bandage roll substantially at the center of the said roll, whereby the said roll forces the arms outwardly so that the arms frictionally embrace the ends of the said roll to prevent excessive and inadvertent unwindi ing of the bandage, their roughened inner faces serving to increase the friction and to pull the loose threads from the ends of the roll when the bandage is unwound.
